lsAsH-Ln--Tralm SPECIFICATION forming part of Letters Patent No. 761,608, dated May 31, 1904.

I Application filed `liebruary 26, 1903. Serial No. 145,268. (No model.) i

To @ZZ whom'J t may concern: Be it known that l, OIiARLEs M.4 RHODES, a

y citizen of the United States of America, residing atfSt'eubenville, in the county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Sash-Lifters, of

which the following is a specification, reference being had therein to the accompanying drawings. i r v My invention relates to certain new and useful improvements in sash-lifters, and aims to produce a simultaneous action or movement of the upper and lower sash in reverse directions when one or the other is actuated. I also propose to provide for. the independent movement of either the upper or lower sash, whereby one or the vother may be raised or lowered .without creating any movement whatever on the opposite one.l

In ,detail thefurther-and other variousobjects of theJ` invention will readily appear in lthe specification and drawings.

. lInt-he drawings, Figure 1 represents a transverse section of one end of the window-frame,

showing the upper and lower sash also in section and partly broken away. Fig. 2 is a sectional view on .theline 2 2 of Fig. 1. Fig. 3 is a section on theline 3 3 ofFig. 2, and Fig. 4

. is a detailed perspective View of the sliding plate. .l l n y The upper sash is designated atl and the lower sash at'2. 3 designates the parting-bead, and 4 the guide-strip located on the outside of the window-frame 5', and 6 designates the inner guide-strip, which, as iswell known, is usually ornamented by beading.

Embedded within the window-frame is a casing 6 of substantially rectangular form and located so as to extend in alinementwith gear-wheel 9 has fixedly secured thereto a beveled pinion 14, which under normal conditions is in mesh with a beveled gear-Wheel 15, carried on a shaft 16. rrfhis beveled pinion is keyed to the4 shaft 16 and is adapted to partake of all of the movements thereof whether rotary or in a horizontal plane. This shaft 16, for a purpose to be hereinafter referred to, l

has movement in a horizontal plane,l and to effect this I secure to on e end of the shaft a bearing 17, which is slidably mounted in guideways 18 19, formed with in turned flanges 2O 21, these guideways being in fixed relation to the side of the casing 6. 'The opposite end of the shaft 16 is suitably secured, as at 22, to a sliding plate 23, adapted to move in a horizontal plane within guideways 24 25, carrying inturned flanges 26 27, substantially` identical with those within which the bearing 17 may move. This sliding plate, as will be perceived from Fig. 4 of the drawings, may be of a substantially rectangular form and is providedv with a slot .24 to readily permit the gear-wheel 9 tov protrude therethrough, this slot being of suflicient Width to permit of a horizontal play'of the plate 23 without thelarged portion 29, suitably bored, as at 30, to

freely receive the shaft 7, and thus in no wise interfering with the movement of the-latter.

Rigidly secured to the gear-wheel 8' is a disk 30, carrying teeth31, adapted for iengagement with teeth of a similar form (designated at 32) carried by the beveled pinion 33, freely mounted onthe shaft 7. It will be noted from Fig...1 ofv the drawingsl that the teeth 32 are so positioned as to engage the teeth 31, and the beveled gear-wheel 15 being -in mesh with the pinionv33 and pinion 14, the latter having suitable connection with the lOO - pendent of the other, and in order to permit 'of beveled pinion 33.

of this desideratum the plate 23, which, as just stated, having connection with the shaft 16, is slid inwardly through the medium of a rod 34, secured thereto for this purpose and which is suitably enlarged to form a hand-grip 35 at its outer end, this inward movement of the sliding plate carrying beveled gear-wheel 15 inwardly out of engagement with the beveled pinion 14, movement of this wheel 15 being permitted by reason of the play existing between the teeth 31 of disk 30 and teeth 32 When in this position, either the upper or lower sash may be raised or lowered, as desired, and this movement will not afect the opposite sash.

v The gear-wheel 9 is provided with a series ofcircumferentially-arranged apertures, (dotted lines, Fig. 1,) adapted to receive a protruding pin 36, carried on one end of the locking- Vrod 37, provided with a hand-grip 38, this rod 37 carrying a collar 39, secured in a depressed portion 4() in the inner end of the casing 6, this rod 37 when slid inwardly causing this pin 36 to engage in one of the said apertures, and thereby lock the gear-wheel 9. This gearwheel may be locked at any position desired, and a multiplicity of apertures may be formed therein in order to permit of various adjustments of the gear-wheel 9. In order to provide for a suitable locking of the opposite gear-- namely, 8-this is also formed with a series of circumferentially-arranged apertures adapted to receive a pin 41, carried on the end of the sliding plate, this pin only engaging in the apertures when the plate is thrown the full distance, such as will be permitted by the distance between the ends of the teeth 32 and the bottom walls formed'by the teeth 31 of the disk 30. In throwing this beveled wheel 15 inwardly sufcient to disengage its teeth from those of the beveled pinion, 14 the pin 41 will not be thrown sufficiently to engage in the apertures of the gear-wheel 8, and this is effected by throwing the sliding plate 23 its full distance.

The invention as illustrated in the accompanying drawings is susceptible to many changes and alterations which will not depart from the spirit and scope of my invention as evidenced thereby` and I therefore do not desire to be restricted to any details illustrated which can be readily altered.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A device of the type set forth, consisting of gear-wheels independently mounted, a beveled pinion secured to one of said gearwheels, a toothed disk secured to the other of said gear-wheels, a beveled pinion carrying teeth adapted for engagement with the said toothed disk, a beveled gear-wheel meshing with said beveled pinions, and means for throwing said beveled gear-wheel in a horizontal plane.

2. A sash-lifter comprising a separate gear for actuating each sash, a separate beveled pinion for each actuating-gear, a shaft on which one of said pinions is fixed, and the other is loosely mounted, a gear interposed between and in mesh with each of said pinions, and means for shifting the bevel-gear out of engagement with the pinion fixed on the shaft and simultaneously locking the loosely-mounted pinion to the shaft.

3. In a device of the type set forth, a gear for actuating each sash, a pinion for actuating each gear, means interposed between and normally in engagement with each of said pinions for simultaneously actuating the same, and means to permit said pinionractuating means to be disengaged from one of said pinions.

4. A sash-lifter comprising an Vactuatinggear for engaging each sash, and a pinion operatively connected to each gear, a shaft mounted for slidable horizontal movement, and a bevelgear on said shaft normally meshing with both pinions, means for shifting thcshaft and thereby the bevel-gear to disengage the said gear from one of the pinions while maintaining its engagement with the other pinion, and means for locking the actuating-gears against movement.

In testimony whereof I aliix my signature in the presence of two witnesses.

CHARLES M. RHODES.
